My old rubber flap scuppers are allowing a lot of water in the boat if most of the weight gets on one side. I was told to replace them with the scuppers that have the ping pong balls in them, but I don't want those because they would stick out on the sides where as my old ones do not. What do y'all use?

I just picked up some new scuppers. The whole assembly was on clearance for $5 at Academy so I replaced them both. They work great now. The rubber was just wore out. They also sell just the rubber flap, but they were $9 each.
